- 2. 2© Cloudera, Inc. All rights reserved. The Essentials of Apache Hadoop The What, Why and How to Meet Agency Objectives Sarah Sproehnle, Vice President, Customer Success
- 3. 3© Cloudera, Inc. All rights reserved.© Cloudera, Inc. All rights reserved. Introduction
- 4. 4© Cloudera, Inc. All rights reserved. What is Apache Hadoop? • Hadoop is a software framework for storing, processing, and analyzing “big data” • Distributed • Scalable • Fault-tolerant • Open source
- 5. 5© Cloudera, Inc. All rights reserved. A Large (and Growing) Ecosystem Impala
- 6. 6© Cloudera, Inc. All rights reserved.

- 8. 8© Cloudera, Inc. All rights reserved. Vendor Integration Platform & Cloud System Integration Data Systems Software and OEM
- 9. 9© Cloudera, Inc. All rights reserved.© Cloudera, Inc. All rights reserved. How it Works
- 10. 10© Cloudera, Inc. All rights reserved. Traditional Large-Scale Computation Traditionally, computation has been processor-bound • Relatively small amounts of data • Lots of complex processing The early solution: bigger computers • Faster processor, more memory • But even this couldn’t keep up
- 11. 11© Cloudera, Inc. All rights reserved. Distributed Systems The better solution: more computers • Distributed systems – use multiple machines for a single job “In pioneer days they used oxen for heavy pulling, and when one ox couldn’t budge a log, we didn’t try to grow a larger ox. We shouldn’t be trying for bigger computers, but for more systems of computers.” – Grace Hopper
- 12. 12© Cloudera, Inc. All rights reserved. Distributed Systems: The Data Bottleneck (1) • Traditionally, data is stored in a central location • Data is copied to processors at runtime • Fine for limited amounts of data
- 13. 13© Cloudera, Inc. All rights reserved. Distributed Systems: The Data Bottleneck (2) • Modern systems have much more data • terabytes+ a day • petabytes+ total • We need a new approach…
- 14. 14© Cloudera, Inc. All rights reserved. The Origins of Hadoop • Hadoop is based on work done at Google in the late 1990s/early 2000s • Google’s problem: • Indexing the entire web requires massive amounts of storage • A new approach was required to process such large amounts of data • Google’s solution: • GFS, the Google File System - described in a paper released in 2003 • Distributed MapReduce - described in a paper released in 2004 • Doug Cutting and others read these papers and implemented a similar, open source solution • This is what would become Hadoop
- 15. 15© Cloudera, Inc. All rights reserved. What is Hadoop? • Hadoop is a distributed data storage and processing platform • Stores massive amounts of data in a very resilient way • Distributes the processing to where the data is stored • Tools built around Hadoop (the ‘Hadoop ecosystem’) can be configured/extended to handle many different tasks • Extract Transform Load (ETL) • BI environment • Predictive analytics • Statistical analysis • Machine learning
- 16. 16© Cloudera, Inc. All rights reserved. Hadoop is Scalable • Adding nodes (machines) adds capacity proportionally • Increasing load results in a graceful decline in performance • Not failure of the system Number of Nodes Capacity
- 17. 17© Cloudera, Inc. All rights reserved. Hadoop is Fault Tolerant • Node failure is inevitable • What happens? • System continues to function • Master re-assigns work to a different node • Data replication means there is no loss of data • Nodes which recover rejoin the cluster automatically
- 18. 18© Cloudera, Inc. All rights reserved. The Hadoop Ecosystem (1) • Many tools have been developed around ‘Core Hadoop’ • Known as the Hadoop ecosystem • Designed to make Hadoop easier to use, or to extend its functionality • All are open source • The ecosystem is growing all the time
- 19. 19© Cloudera, Inc. All rights reserved. The Hadoop Ecosystem (2) • Examples of Hadoop ecosystem projects (all included in CDH): Project What does it do? Spark In-memory and streaming processing framework HBase NoSQL database built on HDFS Hive SQL processing engine designed for batch workloads Impala SQL query engine designed for BI workloads Parquet Very efficient columnar data storage format Sqoop Data movement to/from RDBMSs Flume, Kafka Streaming data ingestion Solr Powerful text search functionality Hue Web-based user interface for Hadoop Sentry Authorization tool, providing security for Hadoop
